Application filed May 21, 1909.

and WILLIAM BURGESS PIERCE, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Machines for Wrapping Commercial Coils'of Wire, of which the following is a full, clear, and exact description.

Our invention relates to machines for wrapping commercial coils of wire by means of ribbons of paper or other suitable material threaded through and wrapped around and around the coils of the same, spirally from the inner to the outer circumference.

The object of our invention is to accomplish this wrapping by means of a ribbon the exposed edge of which is folded under, so as to double the thickness of the paper wound around the coil.

Another important object of our invention is to enable the shuttle, by means of which this wrapping is accomplished, to serve as a magazine for the ribbon used in the wrapping operation and to accomplish the storage of the ribbon therein in such manner that the ribbon may be wound upon and conform to both the concaved and convexed side of a. bobbin, and be unwound therefrom the same as if it was unwound from a cylindrical reel or drum. And a further object of said invention is to adapt it to the wrapping of commercial coils of.

wire of varying diameters and sizes.

This we accomplish in a simple and expeditious manner that does not require the employment of expert help, by the means I hereinafter fully described, and as particularly pointed out in the claims.

In the drawings: Figure 1 is a front elevation of our invention. Fig. 2 is a plan view thereof. Fig. 3 is a longitudinal section through the shuttle of the machine drawn to a slightly larger scale. Fig. 4: is a vertical section taken on line M Fig. 2. Fig. 5 is a transverse section through the central part of thesupporting-frame of the rollers supporting the commercial coil. of wire in position to be wrapped.

through which access is had to its inner circumference, drawn to a slightly larger scale. Fig. 9 is a transverse section of said shuttle, taken on line 99, Fig. 3. Fig. 10 is a detail view showing the manner of-supp'orting one end of the leveremployed to vertically adjust the supporting device of the coil of wire, while being wrapped. Fig. 11 is a plan view of the folding devices of our invention, removed from the machine and drawn full size. Fig. 12 is a front side edge view of the same. Fig. 13 is a longitudinal central section therethrough. view of the discharge end thereof. Fig. 15 is a perspective view of a short strip of ribbon having one edge folded, as when it leaves the shuttle.

Briefly speaking, our invention enables a commercial coil or circular bundle of wire to be placed upon and slowly revolved by a plurality of rollers, and simultaneously Fig. 14 is a wrapped with a ribbon of paper or suitable able side-rails and cross-bars both at the top and near the floor, substantially as shown in Figs. 1, 2 and 4 of the drawings.

Near the center of length of the back of the machine (the side opposite that into which the uncovered coils or bundles of wire are fed to the same),-the upper and lower horizontal rails of the frame are connected by two corresponding guide-columns a, a,

and sliding-1y mounted upon these columns is a carrier-frame B. This carrier consists of two corresponding side-plates whose rear ends are extended upward and are provided with knuckles through'which said columns pass, and whose forward ends are suitably connected by a cross-bar. Near their forward and rear ends these side-plates are provided with bearings for the drums C and D, and midway between these drums we con- The nect the side-plates ofthe carrier by a transverse bolster 6, consisting of a suitable length of steel bar, whose vertically disposedends are secured to said side-plates, above bundles or coils of wire to'be wrapped are seated on rollers C and D, substantially as shown in the drawings, and the rollers E, E,

bear a ainst the sides of the lower portion of sa'i coil and prevent the lateral displacement thereof.

The ournals of rollers C and D are, at

one end, extended beyond their bearings,

and are provided with suitable sprocketwheels D and C, that areconnected by a chain 6, and the journal of the rearwardmost roller'D, opposite its sprocket D, is

connected to or made integral with a shaft F, that extends a suitable distance, and has upon its end a miter gear f, which is actuated by pinion. g revoluble with but adapted to move vertically on .a verticalshaft G. The end of shaft F nearest shaft G is journaled in 'bearin'gsin the end of a lateral.

frame that is secured to and projects from the adjacent side-plate of the carrier near "its rear end. At the base of the upright.

40 portion of this lateral frame it in which the prolast mentioned bearing is made, it is vided with a horizontal extension 72., that is provided with a vertical opening through which shaft G passes, and which serves to hold pinion g in engagement with the gear 7. This manner of keeping pinion g in engagement with gear f is made necessary be- .cause of the vertical adjustability of the ,carrier B. We accomplish this adjustability by' means of. ahorizontally disposed lever,

,H, which latter is fulcrumed at the end of the machine farthest. from vertical shaft G, and at about its center of length is connected to the underside 0fv said carrier, B, by means of vertically disposed links 7'. The

end of lever H opposite its fulcrum-extends beyond the opposite end of the supporting-frame of the machine, and, at a point between the adj acent legs thereof, it has a bolt, I, xtended transversely through it, whose screw-threaded end enters and is secured ina clamping ring J, which latter surrounds and is'adjustable vertically upon a vertically dis-- posedguide-rod K, whose upper and lower :6 ends are secured in cross-bars connecting said legs. Lever H is held out from ring J by means of a leaf-spring one end of which bears against the guide-rod K and the other against said lever. Bolt I, between the lever H and its head, is surrounded by an expansion-spring m, that prevents said lever from slipping outward too far away from ring J, which latter, at a point diametrically opposite that tapped by bolt, I, is provided with a handle a that assists in vertically adjusting the adjacent end of justed vertically, if desired. This we accomplish by mounting the sleeve M, from which the stud forming the fulcrum of said lever projects, upon a vertical guide-rod N,-

and securing said sleeve at any point upon said guide-rod by means of a set-screw O tapped through said sleeve and biting into said rod. I

The upper end of vertical shaft G passes through bearings in the ends of an arm 0 made integral with and projecting from bearings P for the drive-shaft Q, of the ma,- chine, and shaft G terminates just above this bearing, and is provided with a beveled gear 1' that engages and is driven by a beveled pinion p on said drive-shaft. This drive-shaftis, preferably, driven through the medium of a pulley g on its rear end, and said shaft /extends to and has its forward end journaled in bearings q secured to and projecting from the adjacent forward leg of the supporting-frame of the machine. About midway its length the drive-shaft has a channeled wheel R mounted thereon the circumference of whose rear flange s is provided with gear teeth. .In 'the same horizontal plane as wheel R at the opposite end of the machine, and an equal distance from the vertical plane interse'cting the center of length of rollers C and D, there is another channeled wheel S, corresponding in diameter and dimensions to wheel R, and this wheel S also has its rear flange if provided with gear teeth, and is securely mounted upon an idle-shaft T, and said idle shaft has its ends journaled in.suitable bearings secured to and projecting from the adjacent legs of the inachine.

The annular shuttle for wrapping the bundle of coiled wire, is seated in the circumferential channels of thewheels R and S and is revolved thereby, but in order to awaaot prevent the bundle or coil of wire from moving laterally while being wound, we have provided vertically disposed rollers U, whose inclined axes have their ends journaled in lugs o of a frame V, which latter is mounted on the lower end of hangers w, that depend from laterally adjustable plates W secured to the forward surface of the upper rail of the-rear partof the framework of the machine. Said rollers are adjustable toward or from the sides of the bundle or coil of wire by means of horizontal transverse rods w, w, whose contiguous downwardly curved elastic ends press the frames V'carrying said rollers toward said bundle of coiled wire and whose opposite screw-threaded ends are tapped through the lugs of a U-shaped frame X, attached to the rear legs of the frame-work of the machine, in which they are adjusted longitudinally by means of. nuts 3 The shuttle hereinbefore referred to comprises an annulus or ring of greater diameter than the channeled wheels R and S, in

which its periphery is seated, and it has atubular bobbin-section 2 that takes up about three hundred degrees of its length; it is substantially rectangular in cross-section,

. and has the space between the ends of said bobbin-section bridged by a portion that can be displaced topermit of a segment of the coiled bundle of wire being .inserted within its inner circumference. As shown in the drawings, this displaceable portionintersecting the axis of the shuttle. Thesegates have their inner sides curved so as to be concave, when closed, to the curve of the inner circumference of the shuttle, and are secured together by a latch 4,'secured to one side'thereof, as shown in Fig. 8, and their outer sides are cut away so as to permit them to drop into the position shown in dotted lines in Fig. 8 of the drawings, when the coil or bundle of wire is inserted therethrough. The sides of the shuttle are provided with concentric circularv tracks 5 that are adapted to rest upon the circumferential edges of the flanges of wheels R and S, and the rearmost circular track thereof is provided with a series of teeth that engage the teeth of the'rear flange of wheel R and the rear flange t of wheel S thus insuring the positive transmission of the motion of wheel R to the shuttle, and through the latter to wheel S. The sides of gates 3, 3, are pro vided with projecting portions, 6, that form is continuations of tracks, 5, when the gates limit their outward movement.

able fiexible strap, 7 the end edges of which are provided with hooks 8 and 9, that pro- ]ect beyond said ends and catch in suitable openlngs in the metal outer circumference 10 of the ends of said bobbin-section. The

ribbon, 13, of paper or other suitable material, that is inserted in the chamber inclosed within the walls of the bobbin-section, may be zig-zagged back and forth (not shown), but we prefer to take a ribbonthat has been wound upon a drum or cylinder, and make it surround the segmental bobbin, shown in Fig. 7 of the drawings, in themanner shown in F g. 3 of the drawings, in which said ribbon is made to conform to the convex and concave side of the bobbin, in such a way as to store the greatest amount of ribbon in the most compact and smallest space possible. This bobbin consists of a segmental ladder-shaped frame, which is divided about its center of length, into two corresponding sections 14, 14, comprising segmental sideralls that are connected by cross-bars at suitable points along their length, and by rollers 15, 15 whose diameters exceed the width of the side-rails, and which are, pref- 'I erably, located equal distances apart. Each of these sections is, preferably, provided,

with trunnions 16, 16, that consist of cylindrical spindles arranged in alining pairs, and having collars, 17, secured thereto, that The inner ends of these spindles are surrounded by a, sleeve 18, whose length is less than the distance between the rails of the bobbin, and this sleeve and the exposed part of the inner portions of said spindles, are surrounded with a coil expansion-spring 19, whose ends press outward against the collars 17 of the spindles of said trunnions. This construction is adopted so that the trunnions may be compressed toward each other when the bobbin is inserted in the shuttle-section 2, and when the bobbin is in proper position will automatically spread apart and enter openings 20 in the sides of said section 2, about midway between the inner and outer circumferences thereof.

The bobbin is of such length that when in position within bobbin-section, 2, of the shuttle, one end thereof will come nearer the gate 3 than the other, and it is from this last mentioned end of said section 2 that the ribbon is paid out. In order to provide the most convenient construction of the exit end of the bobbin-chamber, for this purpose,

we prefer to close theadjacent end of the same by a transverse partition 21, and to bon around the bobbin (which is immovable with thebobbin-chamber), we provide said chamber with a series of transverserollers 23, that are journaled in bearings in the sides of the bobbin-section adjacent to the inner circumference thereof. After passing out of the opening 22, the ribbon passes between leaf-spring and said partition to prevent its paying out too rapidly ;said spring 25 being secured at its opposite end to a suitable transverse member 26, and having its pressure against the ribbon regulated by means of an adjusting-screw 27. After passing between tension spring 25 and partition 21, the ribbon passes over the outer pivoted end of a tongue which consists of a flat strip of less width than the ribbon, and having its outer portion curved to form a shoulder. The position of this tongue while performing most of its work is inclined from its outer pivoted end to its inner free end, although the latter is free to move so as to accommodate the tongue to the angle assumed by the ribbon as it is wrapped around the coil. The longitudinal edge of'this tongue nearest the rear of the machine is fianged toward the outer circumference of the. shuttleand near its free end this flange projects farther and is then bent horizontally over the end of the tongue to form an overhang bracket 36. Secured to J tudinal edge of the ribbon. In order to accomplish this folding, the width of the companion plate, 32, is made greater than that tongue, and its longitudinal edge 33' nearest the front of the machine, is bent under the corresponding edge of the tongue, thus forming a passage that finishes the fold of the forward edge ofthe ribbon while in transit betweensaid plates. The commencement of the fold for the edge of the ribbon is'made when the ribbon is moving over the curved shoulder at the pivoted end of the tongue.

This as shown in Figs. 11 and 12 of the drawings, starts the fold in an easy manner,

and permits the rlbbon to run easily and.

shuttle arranged at right angles thereto, and placed, so that as it revolves it will revolve through the eye of the said coil, power is imparted to the machine, and, while the said coil of wire revolves slowly, the shuttle will revolve rapidly and wrap said ribbon with its forward edge folded under, around and around said coil, from the inner circumference to-the outer circumference thereof, the

entire endless length of the coil, whereupon themachine is stopped; the ribbon cut off and the end thereof tucked under one of the bights thereof to prevent it from unwinding. The gates of the shuttle are then opened and the wrapped coil removed, and then an uncovered coil or bundle is inserted in place in the machine; the gates of the shuttle are closed and locked, and the wrapping of the last inserted coil proceeds as hereinbeforo stated. In the operation of the machine thus briefly explained 'the parts thereof operate and perform the functions hereinbefore fully explained. In order to support the shuttle when the displaced portion thereof is lowermost, and to steady it while in motion, we prefer to provide the rear surface of tracksfi of the shuttle with a rearwardly projecting concentric flange, and in the longitudinal vertical plane of the axis of the shuttle provide anupper and lower idle wheel 37 and 38, that, respectively, en-

gage the inner and outer circumference of said track flange. If desired, the upper wheel 37 may have a stepped portion of less diameter on its forward side that may engage the crowns of the ear teeth of said flange, 5., These idlers, 3 ai1d38, are journaled on suitable studs, secured to artd projecting from the vertically disposed end of a bracket 39, secured to and projecting from the center of length of the rear upper rail of the supporting frame of the machine.

It will, of course, be obvious, that our improved machine may be used to wrap similar shaped bundles of other materi'al than wire. We wish to be understood as contemplating the use of our machine for all such purposes, and although the description of our invention has hqrein specifically ,referred to coils of wire, we desire to com- -prehend its applicatlon to all purposes to which its functions adapt it.

What we claim as new is 1.
